RightCaller: AI Spam Blocker

RightCaller tells you who's calling and why you should — or shouldn't — pick up.

Unknown number? RightCaller checks it the moment it rings and gives you a clear verdict: Looks fine, Be careful, or Blocked. No guessing, no answering just to find out.

WITHOUT UPLOADING YOUR CONTACTS
Most caller ID apps are built on everyone's address book. RightCaller is not. Three numbers you can check:

0 — contacts uploaded, ever. Matching happens on your phone.
3 — permissions, and no more: calls, notifications, contacts. No SMS. No microphone.
6 — checks that run with no signal at all, entirely on this phone.

AI THAT EXPLAINS, NOT JUST BLOCKS
Most blockers give you a number and a shrug. RightCaller names the scam pattern — premium-rate callback, bank impersonation, delivery-fee, tech-support, "wrong number" openers — and tells you in plain English how it works and what to do.

WHAT YOU GET
• Instant caller verdicts on unknown numbers, before you answer
• Scam-type intelligence: the pattern named and explained
• Reverse lookup: check any number's reputation in seconds
• Every screened call in one line, expanding for the full reason — report, block or text back in two taps
• Silence unknown callers during focus hours, with an "expecting a call" override
• Custom block rules in plain English ("block international calls after 9pm")
• A weekly digest of what RightCaller stopped for you

PRIVACY, HONESTLY
RightCaller never listens to, records, or transcribes any call — that is not something we do, and not something a third-party app can do. Your contacts never leave your phone. When we check a number's reputation, only a one-way hash is sent — never your address book, never your call history. Screened calls are kept on your phone for 30 days and nowhere else.

FREE AND PRO
Free: on-device screening, block and allow lists, caller verdicts, reverse lookup. Complete, and it stays that way.
RightCaller Pro adds three things: AI scam-type detection, natural-language block rules, and focus windows. Nothing is taken away from Free.

RightCaller is a caller ID and spam-blocking app. It is not a dialer and not an SMS app.
